This makes it challenging to use image signing in environments which don’t rely on Docker Hub. If you want to use it with a private registry, you must also deploy your own Notary server. Notary currently works in tandem with the registry. GitHub, GitLab, and popular cloud deployment platforms have all started to offer integrated registries. It’s designed for Docker Hub first and foremost whereas today you may be using registries from many different providers. The original version of Notary was developed before the proliferation of Docker registries observed today. All this functionality is built into the existing Docker CLI under the docker trust command group. Other users can verify the image by asking the registry to match its public key against the data they’ve pulled. The current iteration works by adding your public key to your registry, signing your image with the key’s private counterpart, and then pushing the signed image up to the registry.
